Abstract

The effects of cutting edge shapes on the phenomena of rubbing and ploughing in nano-abrasive machining were investigated. The shapes under investigation include flat, spherical and trapezoidal shapes. The tool with the flat end geometry shows a fast initiation of ploughing, because it has the largest surface area to engage more atoms. It doesn’t show rubbing phenomenon at the (initial) depth of cut of 0.5 Angstroms. The tool with the trapezoidal end has the lowest average cutting force and the tool with the flat end has the highest average cutting force.
